Question

我正在开发一个使用Rest api来管理露天工作流程的Web应用程序，在我的流程中，我有一个具有flow22条件的专用网关，如下图所示：（如果决策变量等于＆＃39;批准＆＃39;流程转移到任务3）

对于第一个和第二个任务一切正常，除了我在使用Rest完成task2时遇到此错误，知道我已经设置了我的变量以批准。这是我的bpm

如何通过Rest api处理独占网关？提前谢谢。

Answer 1

我强烈怀疑决定变量已经设置，在完成 task2 之后，您可以通过调用此端点来检查变量的值：

GET /tasks/{taskId}/variables

要在完成任务之前设置变量，你必须这样做

<强> URL：

PUT /tasks/{taskId}?select=state,variables

请求正文：

{
  "state": "completed",
  "variables": [
      {
          "name": "decision",
          "type": "d_text",
          "value": "approve",
          "scope": "global"
      }
  ]
}

Answer 2

有很多解决方案：

您可以在flow14“$ {pfewf_avisRespTech！='Refuser'＆amp;＆amp; pfewf_avisRespTech！='A Rectifier'}”中使用此条件。
在您的模型中，将pfewf_avisRespTech的默认值设置为“Valider”，例如
在要求工作流引擎完成任务之前，请他更新pfewf_avisRespTech的值
在task2的完整监听器中检查“pfewf_avisRespTech”的值，如果它等于“”或null给它一些值。
